- On IRIX systems, this routine is in lliibbffoorrttrraann..ssoo which is linked by
- default when compiling programs with the MIPSpro 7 Fortran 90 compiler
- or when compiling programs with the --ccrraayylliibbss option to the MIPSpro
- F77 compiler.
-
- The PPXXFFGGEETTCCWWDD subroutine uses the ggeettccwwdd(()) function to get the current
- working directory.
-
- When using the CF90 compiler or MIPSpro 7 Fortran 90 compiler on
- UNICOS, UNICOS/mk, or IRIX systems, all arguments must be of default
- kind unless documented otherwise. On UNICOS and UNICOS/mk, default
- kind is KKIINNDD==88 for integer, real, complex, and logical arguments; on
- IRIX, the default kind is KKIINNDD==44.
-
- The following is a list of valid arguments for this subroutine:
-
- _b_u_f An output character variable or array element for the
- current working directory. The longest pathname cannot be
- longer than PPAATTHH__MMAAXX for the UNICOS operating system, or
- MMAAXXPPAATTHHLLEENN for IRIX systems as defined in <<ssyyss//ppaarraamm..hh>>.
-
- _i_l_e_n An output integer variable containing the character length
- of _b_u_f.
-
- _i_e_r_r_o_r An output integer variable that contains zero if the working
- directory path was successfully copied into _b_u_f or nonzero
- if PPXXFFGGEETTCCWWDD was not successful.
-
- The PPXXFFGGEETTCCWWDD subroutine may return any of the following error values:
-
- EETTRRUUNNCC If the length of _b_u_f is less than the complete path
- length.
-
- EEAACCCCEESSSS If read or search permission for any component of the
- current working directory path was denied.
-
- EEXXAAMMPPLLEESS
- In this example, PPXXFFGGEETTCCWWDD will be called with a large buffer, which
- should not cause any errors, and then with a very small buffer, which
- should cause an error.
